Missing Cloth Paint Panel in 2019.3

2019.2 all version cloth simulation made all broken
so i want to use 2019.3.0b11 version to fix it , but in this version when i click edit cloth constraints button there are no paint panel in editor view

Getting same in Unity 2019.3.3f1 - When clicking on ‘Edit Cloth Constraints’ the ‘Cloth Constraints’ panel does not appear.

Has anyone found a solutions for this? I’ve seen some suggest changing the layout to default but this did not resolve the issue for me.

It says “Layout” at the top right, you need to turn it to “Default”, all the problem will be solved, the point I have shown with the green rectangle is in the attached picture.
